Arc Scale

An Arc Scale is the main visual element of a Circular Gauge, because it contains all other elements (e.g. Needle, Marker, Custom Labels, etc.).

A Circular Gauge can contain either a single or multiple Arc Scales. If there is more than one scale in a gauge, then they can be arranged either one into another...

... or side-by-side.

For more information on an Arc Scale, refer to the Scales document.

The table below lists the main properties affecting element behavior and appearance.
